You wont see dots on sky, cause sky is not a wall. You might see many tiny beams in air - each for every dot .. but that's all.
Usually it's not possible to create custom images. Such laser gratings are made by creating very fine structure on glass, it's not doable at home. The main beam is bended into different direction by interference.
If you want solid laser, get one from forum members, or get parts and build one, if you are at least a bit into electronics. It will be cheaper, more powerful, and more reliable. On the other hand you might have troubles mounting those gratings on it. We here don't like Wicked Lasers at all, and we discourage anyone from buying there. But if their lasers have some good point, it's the mount a supply for different optics.

But it's cheaper yes.... durabillity i don't know, not much reviews around.
This laser gutted, not much info around also.

Funny thing is, when someone starts a topic about buying a lazerer rifle.. people also say to buy from this forum first...
And when someone wants to buy a WL, they say to buy the rifle.
I don't get it...

If you really want a WL S3 with lens kit either 445nm blue Arctic or 532nm green Krypton go for it but is going to cost lot more than any of the above. The high power Krypton 750+ is $999.95 plus lens kit and shipping---even the 500+mw is $799.95 + lens kit and shipping.

Have you considered JetLasers PL-E --pretty much best in the business quality, reasonable prices, focusable, + outstanding customer service? http://jetlasers.org/

Here are two 445 blues that you can buy for a lot less than a WL and the first one is available in what they call a 2000mw model and say is really 1500+---the second is called a 1000mw but they say is reallt 1200-1500mw--both are at very reasonable prices. Just a couple of ower cost thoughts.

If you really want a WL S3 with lens kit with 445nm blue Arctic or 532nm green Krypton go for it but is going to cost lot more than any of the above. The high power Krypton 750+ is $999.95 puls lens kit and shipping---even the 500+mw is $799.95 + lens kit and shipping.

Some great lasers there with great reviews and very reasonble on price, but why are green lasers SO much more expensive than blue ones? Will a blue laser be really really visable at night? At distance?

No they are just cheap.
Simply put, and can't match green at distance

Wich comes to the question: is WL expensive...

yes they are sinds blue diodes are so comon these day's and you can get better here in output terms..

Was just attempting to lay out a range of choices that are OK examples of what is out there, as the chappy said he was a 1st time laser guy

Yes seems he wants a 532nm green but at first wanted a 445 blue Arctic so I mentioned the AliExpress stuff. They are the same Chinese lower cost lasers as sold by several vendors but at better prices--I did include a included a low cost green.

If he decides more expensive 532nm --then the WL Krypton and lens kit or a JetLasers w/o lens kit are there for the buying. Certainly the resale value of either WL or JetL is much better than others

Ok I really know nothing about laser spec apart from more watt = more power and brightness right?

I just want it to be really really bright, so if I shine it up into the air people miles away will see it, I'm not sure if blue a good colour for that even @ 1MW?

Also the green lasers don't come with lens so I'm not sure if I can buy lens to attach or something... cmon guys help me out a bit more lol.

Also at what height / distance will the laser no longer become visible?

I assume you meant 1000mw/1W as in S3 Arctic.

Here read about flashing the Space Station with a Wicked Lasers S3 Arctic 1000mw/1W . The space station at it's nearest approach was 310 miles from earth---is that far enough away for it still to be visable for you?http://laserpointerforums.com/f44/am...ser-72271.html

Yes a 1000mw/1W blue is very visible however. Maybe look into a blue laser build by a forum member---there are several in the 2W+ range offered which is very bright and also very dangerous---occular damage such that you are blind forever can happen in less than 1/4 second faster than the human blink reflex with these lasers--if an accident or mistake occurs there is no time or ability for you to correct --happens too fast.
So with high output power you need goggles and you need experience to know what you are doing. You need to study up on those aspect if you are going to buy a powerful laser--they are not toys. Relatively eyesafe laser according to government regualtions are 1mw in some places and <5mw other others--so what you have been talking about is seriously more powerful.

Can you project images/pattern on clouds under the best atmospheric conditions with one--probably not powerful enoguh for that

Visibility is a multi factor thing and dependent on atmospheric condtions as much as wavelength and output power.

What is it you actually want to do or achieve in the real world?

I just want to have fun with it, I mean with lasers in general there isn't much of an objective other than to just mess around with it (safely) and I'm very well aware of the dangers which is why I will purchase glasses also.

I quite like the idea of projecting an image or a beam of light up into the sky and know that hundreds of thousands of people will see it and wonder what it is and where it's coming from.

Also I'll use it as an insta mosquito exterminator for when the summer comes around

I'll check on the forums but I think people are only selling the parts to make lasers? Nevertheless I'll check around. I have no problems buying a home made laser from someone trusted on the forums.

"hundreds of thousands of people" ??

Will people be able to see a beam for a mile or more around you when atmospheric conditions are optimal--probably yes if looking in the right direction. Can also attract the local authorities/constabulary who tend to confiscate same.
"UK and most of Europe are now harmonized on Class 2 (<1 mW) for General presentation use laser pointers or laser pens. Anything above 1 mW is illegal for sale in the UK (import is unrestricted). Health and Safety regulation insists on use of Class 2 anywhere the public can come in contact with indoor laser light, and the DTI have urged Trading Standards authorities to use their existing powers under the General Product Safety Regulations 2005 to remove lasers above class 2 from the general market"

You really need to look into whatever aspects you want to know about using search---lasers are a whole field of study and technologies--and govern yourself accordingly.

Nobody has enough time to be able to spoon feed you all the answers especially where an answer is a complicated question about a hypothetical situation which may or may not ever exist.

You have to actually look in the Buy, Sell ,Trade section to know there are many complete lasers built and sold by LPF members. There is some really exceptional work being done by members.
See: Buy, Sell, & Trade - Laser Pointer Forums - Laser Pointers and Laser Pointer info
Is worth a look there have been some really nice 2W+ 445nm blues sold as recently as today --hobbists rarely bulid 532nm green but sometime sell greens.
